Please hurry and I will give you brainlest if your show your work Dave has outgrown the bike he rode when he was small. So, for his twelfth birthday, his parents surprise him with a five-speed Blaze Rider 2000! Dave has never had a bike with multiple speeds before, and he is eager to learn how it works. He starts by testing the middle speed. There is a proportional relationship between the number of times Dave pedals, x, and the number of times the wheels rotate, y. What is the constant of proportionality? Write your answer as a whole number or decimal. wheel rotations per time Dave pedals

The constant of proportionality is 2.

Step-by-step explanation:

All the y values are twice as much as the corresponding x values

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
